GAS-MASK.
Specification of Letters Patent.
Patented Apr. 1, 1919.
Application flied June 1, 1918. Serial No. 237,749.
To all whom it may concern.'
Be it known that I, PANKRAGY WAsYLo- WIoH, a subject of the Emperor of Austria, residing at Chelsea, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Gas-Masks, of which Athe following is a specification.
The primary object of the invention is the provision of a simple and inexpensive device readily attached to a persons body for instant use in enabling the wearer to breathe when the atmosphere is lled with gas, such as during a gas attack of the enemy.
A further object of the invention is to provide an air filtering means readily carried by a soldier in connection with a breathing apparatus whereby gas laden air is purifiedl for breathing so as not to injure the lungs of the soldier wearing the device.
In the drawing:
Figure 1 illustrates the manner in which the device is worn by a person for assistance in breathing;
Fig. 2 is a central longitudinal sectional view of the ilter slightly enlarged; and
Fig. 3 is a transverse sectional viewthereof.
My invention includes a mask 10 formed of rubber or similar material and secured to a helmet 11 whereby the mask will tightly engage the face of the wearer by reason of its resiliency when the helmet 11 is placed upon the head. Eyeglasses 12 are provided for the mask 10.
l A tube 13 is attached to the said mask for supplying air therethrough, but by means of a connecting pipe 14 having a jointed connection therewith at one end as at 15, while the opposite end of the pipe 14 is secured to an air ilter 16 by means of a similar detachable joint 17. A ring 18 is provided for mounting the filter 16 upon the ankle of a person such as the soldier 19, indicated by dotted lines in Fig. 1 of the drawing.
, The soldier being provided with the usual fan 20 agitates thev air adjacent the filter 16 so that the air passes through the perforations 21 in the bottom block 22 of the filter and thence through gas filtering means or packing 23 and through perforations 24- in the opposite end block 25 of the filter and thence to the neck 26 of the filter to which the pipe 1-1 is connected. The blocks 22 and 25 are secured to opposite ends of a connecting shank 27, while a ieXible covering 28 surrounds the said blocks and holds the filtering medium 23 within the covering 28 surrounding the said shank 27.
The block 22l has a concaved inlet end 29, while the block 25 has a recessed outlet end 30, the latter opening into the said neck 26 which is preferably formed as a continuation of the flexible covering 28, which covering is also slightly elastic. The pipe 14 may be provided of any desired length to be varied according to the height of the individual wearing the device, the dierent parts ofthe device being readily renewable at will. Annular beads 31 are provided upon the block 25 over which the resilient neck 26 is snugly fitted, while a fiange 32 at the opposite end of the flexible covering 28 overlies the concaved end 29 of the block 22 and whereby the device is retained assembled with the block 25 secured to the shank 27 and the lling 23 inclosed within the said covering 28.
The wearer of the device can readily see through the glasses 12 and is unimpeded in his movements while wearing the device. The device enables a soldier to tight the enemy during a gas attack and the device is light in weight, convenient for carrying and is easily manufactured.
What I claim as new is A lter for gas masks consisting of a shank, a block at one end thereof having a concaved outer entrance end provided with air receiving perforations therethrough, a block at the opposite end of the shank having a recessed outlet end with perforations through said last named block, a resilient covering overlying both of said blocks adapted for maintaining the outlet block upon said shank and having an outlet neck' portion adjacent said recessed end, and gas filtering medium within the said covering and surrounding said shank.
In testimony whereof I aflix my signature.
PANKRACY WASYLOWICH.
